20 Review

Cancer staging is a rating by your

doctors of how far the cancer has

grown and spread. The rating is

based on test results. Doctors plan

additional tests and treatment based

on how much the cancer has grown.

In Part 2, the scoring system used for

cancer staging is explained.

TNM scores

The AJCC (

staging system is used to stage esophageal cancer. In

this system, the letters T, N, and M describe a different

location of cancer growth. Your doctors will assign a

score to each letter. TNM scores will be combined to

assign the cancer a stage. The cancer stage is used

to assess the prognosis of the cancer and to decide

what treatments will be used. A prognosis is the

outlook (prediction) of the pattern and outcome of a

disease.
